Event Information

Well established as Guildford’s favourite trail running series, the original aat: event The G3 series will return to Newlands Corner for it’s 16th year in 2021, sponsored by Fitstuff run shop.

Named after the “3 peaks of Guildford”, the Fitstuff G3 series is a collection of 3 winter races set in the beautiful Surrey hills. During your race, expect muddy hills, steep inclines, beautiful views and technical descents, weave your way through woodland and frosty fields and brace yourself to climb your way to the top of one of Surrey’s highest hills where you’ll be rewarded with a panoramic view of up to 7 different counties!

Most importantly – at the finish line you will be rewarded with one of our amazing medals (make sure you collect all 3 ) and our famous finish line homemade flapjack’s and brownies.

The Fitstuff G3 Series is a long-standing favourite, so enter well in advance to make sure you don’t miss out!
